    Working principle of explosion-proof chain hoist and precautions required during use


Description: Explosion-proof chain hoist is a manual lifting tool with explosion-proof performance, simple operation, and easy to carry, especially for non-power operation and open-air operation, used for lifting goods and vehicle loading and unloading, and more convenient.

Explosion-proof chain hoist is a manual lifting tool with explosion-proof performance, simple operation, and easy to carry, especially for non-power operation and open-air operation. It is more convenient for lifting cargo and loading and unloading vehicles.

Working principle of explosion-proof chain hoist:

It pulls the hand chain and the hand sprocket to rotate, and presses the friction plate ratchet and the brake seat into one body for common rotation, and the long tooth shaft rotates the plate gear, the tooth short shaft and the spline hole gear.

Lifting, the operator stands on the side of the hand chain wheel and pulls the hand chain downward to rotate the hand chain clockwise. Therefore, the hand chain wheel is driven by the transmission gears to rotate the lifting chain wheel, and the lifting chain drives the goods to lift. . Under the action of the brake, it is guaranteed that the cargo can stay in any position in the air without falling down by itself.

When descending, pull the other bracelet down to make the bracelet wheel rotate counterclockwise. At this time, the pawl releases the ratchet wheel, and it can descend smoothly under the action of its own weight such as the lower hook. When the bracelet stops pulling, the brake immediately resumes the braking function, so that the goods can be stopped at any position.

The explosion-proof chain hoist can be directly hung on a fixed point and used as a fixed-point fixed fixed type. It can also be equipped with an explosion-proof operation trolley to slide on a single beam track manually as an explosion-proof manual hoist.

The hoisting capacity of explosion-proof chain hoist is available in various specifications such as 0.5 ton, 1 ton, 1.5 ton, 2 ton, 3 ton, 5 ton, 7.5 ton, 10 ton, 15 ton, 20 ton.
